The Canadian rockers went full-on retro in the vid, taking us back to 1964 with a vintage aesthetic a bubblegum pop sound.

The guys of the group opened up about what inspired this nostalgic song and its visual counterpart, saying:

"The video for Singing In The Rain is a love letter to one of our favourite movies of all time, That Thing You Do. It's about the exhilarating power that 3 chords, a drum beat and a catchy melody can have on the lives of the people who create it. The video takes you on the magical journey from rehearsing in a garage to playing stadiums and topping the charts. and the roller-coaster ride that is the music industry: both exhilarating and extraordinary, heartbreaking and bittersweet. We had a blast filming this video and we hope that you will enjoy it and that it will make you smile!"

Ch-ch-check out the music video for Simple Plan's latest single off their new album Taking One For The Team (above)!

Off the band's upcoming 14-track album Taking One For The Team, the single is a perfect anti-love letter about some girl named Sofia — we're not sure what she did, but frontman Pierre Bouvier CLEARLY isn't happy about it!

One thing's for sure, you can plan to be brought back to a simpler time (get it?!) by rocking out to this song!

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
